Found that the cause was that `React.useId()` returns the same value across requests whereas it was being used to create a unique key. On further inspection that code could be removed altogether as `id` was not used client-side and the `rscCache` map is no longer needed as the flight instance is already being created per request so it can live in the context of the request execution.

This PR updates the server components documentation to make it more clear the benefit of server components and what their current status is inside Next.js.
It removes code snippets and CTAs for trying them out, as things have changed with the Layouts RFC since these docs were previously written. With the upcoming changes, server components will now be the default inside `app`. The list of supported and unsupported features was no longer accurate.
We will be providing more guidance as the layouts and routing changes are ready to be tested.
[Read the Layouts RFC](https://nextjs.org/blog/layouts-rfc) for more details.
This ensures we ignore all except the files/directories we are explicitly wanting to watch to prevent watching/considering directories with massive amounts of files slowing down startup.

Added missing trace for `client-full-reload` event in hot reloader. Full
reload tests moved to hmr, think they make more sense there than on
their own.
The PR fixes#40388.
Currently, `next/dynamic` will try to provide a default `loading` to the
`loadableOptions` even when `suspense` is enabled, thus triggering the
incorrect warning. The PR fixes that. The corresponding integration test
case is also updated.

This serves to add support for [Subresource
Integrity](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity)
hashes for scripts added from the new app directory. This also has
support for utilizing nonce values passed from request headers (expected
to be generated per request in middleware) in the bootstrapping scripts
via the `Content-Security-Policy` header as such:
```
Content-Security-Policy: script-src 'nonce-2726c7f26c'
```
Which results in the inline scripts having a new `nonce` attribute hash
added. These features combined support for setting an aggressive Content
Security Policy on scripts loaded.

For edge routes in app dir, we passed the page name as url so that the
url will be incorrect:
* a non-dynamic route `/dashboard` will become `/dashboard/page`
* a dynamic route `/dynamic/[id]` with url `/dyanmic/123` will still hit
`/dynamic/page/[id]/page`
This PR uses normalized `params.page` with interoplated as correct
pathname for the page.
Hello,
Just update the docs to be aligned with the current middleware implementation 🙂

When a client module is imported by both a module from an `app` entry and a module from `pages` entry, it is possible that it is included in the `pages` chunk eventually. The current check makes the manifest incomplete in that case.

Given the change in #40076, when a middleware rewrites into an Edge
API route and changes the querystring, the changed querystring does
not appear in the incoming NextRequest object in the Edge API route
```ts
// middleware.ts
export function middleware(req: NextRequest) {
const url = req.nextUrl;
url.pathname = "/api/hello";
url.searchParams.set("foo", "bar");
return NextResponse.rewrite(url);
}
// pages/api/hello.ts
import { NextRequest } from "next/server";
export default function handler(req: NextRequest) {
return NextResponse.json(req.nextUrl.searchParams.get("foo"));
}
export const config = { runtime: "experimental-edge" };
```
Our expectation when requesting `/api/hello` is to see `"bar"`,
but instead we are getting `null` back.
This commit fixes this issue by reading the given `query` instead of using
the initial querystring provided with the user request (prior to rewriting)

Makes it possible to switch between edge/server runtime in dev without
breaking the server.

#### middleware-plugin.ts
`middlewareManifest` moved from module scope to local scope. Stale state
from earlier builds ended up in `middleware-manifest.json`. Functions
that changed from edge to server runtime stayed in the manifest as edge
functions.
#### on-demand-entry-handler.ts
When a server or edge entry is added we check if it has switched
runtime. If that's the case the old entry is removed.
#### Reproduce
Create edge API route and visit `/api/hello`
```js
// pages/api/hello.js
export const config = {
runtime: 'experimental-edge',
}
export default () => new Response('Hello')
```
Change it to a server api route and visit `/api/hello`, it will explode.
```js
// pages/api/hello.js
export default function (req, res) {
res.send('Hello')
}
```
#### Bug not fixed
One EDGE case is not fixed. It occurs if you switch between edge and
server runtime several times without changing the content of the file:
Edge runtime
```js
export const config = {
runtime: 'experimental-edge',
}
export default () => new Response('Hello')
```
Change it to a server runtime
```js
export default function (req, res) {
res.send('Hello')
}
```
Change back to edge runtime, the content of the file is the same as the
first time we compiled the edge runtime version.
```js
export const config = {
runtime: 'experimental-edge',
}
export default () => new Response('Hello')
```
The reason is that both the edge and server compiler emits to the same
file (/.next/server/pages/api/hello.js) which makes this check fail in
webpack:
https://github.com/webpack/webpack/blob/main/lib/Compiler.js#L849-L861
Possible solution is to use different output folders for edge and server

Currently the DEV server can't recover if you export an invalid runtime
config. It ends up in a state where it stops to work but nothing is
printed to the terminal.
It now prints an error but keeps working. When building it should crash,
there's an existing test for that
https://github.com/vercel/next.js/blob/canary/test/production/exported-runtimes-value-validation/index.test.ts#L5-L17
#### Reproduce
```tsx
export default function Page() {
return <p>hello world</p>
}
export const config = {
runtime: 'something-odd',
}
```
Fix the ssr/ssg detection when you export a nextjs data fetching method
as a variable instead of an async function.
- [x] Add case support in `checkExports`
- [x] Add unit tests for `getPageStaticInfo`
